Answer 1

Answer:

28cm

Step-by-step explanation:

Hi!

Let's find the area of the rectangle (we can form) and then tack on the area of the triangles.

We have 4 * 3 = 12. So the first area is 12.

Now, the triangles. We see that they will have base 4, and leg 2.

Using the Pythagorean Theorem:

4² + 2² = 20. √20 = 2√5. That won't really matter however, because we will multiply 4 by 2 to find the area.

4 * 2 = 8

The same will happen on the other side:

4 * 2 = 8 (note that we could've created a rectangle out of the triangles, but that would give us 16 too.)

8 + 8 = 16.

16 + 12 = 28

Thus, the area is 28 cm.

Hope this helps!
